    摘要： A chain organopolysiloxane is obtained by polymerizing a fluorine-containing cyclotrisiloxane of the general formula: ##STR1## (wherein R.sup.1 is a monovalent hydrocarbon group, and Rf is a perfluoroalkyl group or perfluoroalkyl ether group)in the presence of a lithium silanolate catalyst, silylating the resulting polymerization product, and treating the silylated product at a temperature of not lower than 100.degree. C. under a reduced pressure of not higher than 10.sup.-1 mmHg to remove volatile components therefrom. The organopolysiloxane is essentially free of volatile low-molecular siloxanes. Therefore, the chain organopolysiloxane can be used without the problems which might arise from the volatile low-molecular siloxanes, such as evaporation of low-molecular siloxanes from a cured rubber product with the result of electrical-contact troubles.
